SEPARABLE HINGE FORSCREENS. Y

SPECIFICATION forming part of Letters Patent No. 754,770, dated March15, 1904.

Appiioaaoo nod Novombor 24,1902. sonoi No. 132,664. No model.) v i i Toall whom, t may concern:

Be it known that I, HENRY B, HIGGINS, a resident of Denver, in thecounty of Arapahoe and State of Colorado, have invented certain new anduseful Improvements in Separable Hinges for Screens, of which thefollowing is a specification.

rFhis invention relates to means for hanging or pivoting half-sizescreens in windows; and the obj ect of the invention is to provide meanswhereby a half-size screen may be detachably pivoted within awindow-frame and hung over the lower sash of the window. The particularobject of my invention is to provide a cheap and readily-attachablescreen pivot or hanger.

My invention consists in the combination of the window frame and screen,with horizontally and vertically slotted boxes secured to said frameabove the screen and plates secured to the upper rail of said screen andprovided with upwardly and outwardly extending arms pivoted in saidboxes; and my invention consists, further, in various details ofconstruction and in combinations of parts, all as hereinafter described,and particularly pointed out in the claims.

The invention will be more readily understood by reference to theaccompanying drawings, forming a part of this specification, and inwhich- Figure l is a vertical section of a window equipped with a screenhaving attachments or hangers embodying my invention. Fig. 2 is ahorizontal section on the line a' m of Fig. 1. Fig. 3 shows the screenhung between the blind-stops of the window-frame. Figs. 4 and 5 show theright and left hanger-boxes, and Figs. 6 and 7 illustrate thecorresponding pivot-plates.

As shown in the drawings, 2 represents the window-frame containing theupper and lower Sash 4 3. 5 is the blind-stop, and 6 represents thescreen-frame containing the screen fabric 7. When the screen is placedagainst the blind-stops 5 of the window,'the gap between the upper railof the half-size screen and the opposite sash is closed by a strip 8.When, on the other hand, the screen is arranged between the oppositeblind-stops, no such strip is required, as the screen rests against thelower rail of the upper sash, as shown in Fig. 3. K My hanger orattachment is applicable in either case. The hanger comprises two pairsof devices for opposite sides of the screen, arranged at the uppercorners thereof. These devices are the boxes 9 and the pivot-plates 10.The boxes 9 may be castings; but I prefer to stamp or form them fromsheet metal, as shown in the drawings. Each is provided with ahorizontal slot 11 and a vertical slot 12, the latter merging into theformer, whereby each box is constituted an inverted hook to receive thepivot portion 13 of the plate 10. The boxes are formed oppositely, sothat their slots deliver outwardly-that is, the boxes are right and leftto allow the screen to be hung from the outside of the window.

The hanger-plates 10, which are attached to the upper corners of thescreen-frame, are formed from sheet metal, the pivot portions 13 beingmade by rolling the upwardly and outwardly projecting angle portions ofthe plates. The plates proper are preferably provided with spurs 14 tosink into the frame. The boxes and the plates are secured by screws ornails driven into the sides of the windowframe and the top of thescreen-frame, respectively.

These attachments are cheap to manufacture, are strong and durable, andare neat in appearance. When the screen is hung in the boxes, it isobvious that it may be swung outwardly with ease or may be easilyremoved from the window.

As various modications of my invention will readily suggest themselvesto one skilled in the art, I do not confine lmy invention to thespecific constructions herein shown and described.

Having thus described my invention, I claim as new and desire to secureby Letters 'Patentl. A separable hinge for screens comprisinghorizontally and vertically slotted boxes adapted to be secured to thewindow-frame above the screen-frame and hanger-plates adapted to besecured upon the top of the screen-frame and having upwardly andoutwardly extending pivot-arms adapted to be held in said boxes,substantially as described.

2. The window-screenhanger comprising IOO the inverted-hook boxes andthe hanger-plates having curled ends constituting pivots, substantiallyas described.

3. A separable hinge for screens comprising sheet-metal hanger-boxesadapted to be secured to the window-frame above the screen andsheet-metal plates adapted to be secured to the top of the screen andhaving the upwardly and outwardly bent curled arms piv oted in saidboxes, substantially as described.

4:. A separablefhinge comprising boxes constructed to form hooks andadapted to the sides of a window-frame above the top of a screen, andpivots adapted to be secured to the top of a screen, each of said pivotscon'- sisting of a sheet-metal base portion attachable to a screen andan integral curled or rolled portion projecting upwardly andhorizontally from the base and adapted to pivotally engage said hooks.

5. A separable hinge-pivot adapted to be secured to the top of a screen,said pivot consisting of a sheet-metal base portion 'and an HENRY B.HIGGINS.
